- Femoroacetabular Impingement and Acetabular Labral Tears - Part 1: Pathophysiology and Biomechanics(2020) EJNISMAN, Leandro; RICIOLI JÚNIOR, Walter; QUEIROZ, Marcelo Cavalheiro; VICENTE, Jose Ricardo Negreiros; CROCI, Alberto Tesconi; POLESELLO, Giancarlo CavalliAbstract Femoroacetabular impingement (FAI) is an important cause of hip pain, and the main etiology of hip osteoarthritis in the young population. Femoroacetabular impingement is characterized by subtle alterations in the anatomy of the acetabulum and proximal femur, which can lead to labrum tearing. The acetabular labrum is essential to the stability of the hip joint. Three types of FAI were described: cam (anespherical femoral head), pincer (acetabular overcoverage) and mixed (characteristics of both cam and pincer). The etiology of FAI is related to genetic and environmental characteristics. Knowledge of this condition is essential to adequately treat patients presenting with hip pain.
- Femoroacetabular Impingement and Acetabular Labral Tears - Part 3: Surgical Treatment(2020) QUEIROZ, Marcelo C.; RICIOLI JUNIOR, Walter; EJNISMAN, Leandro; GURGEL, Henrique Melo de Campos; MIYAHARA, Helder de Souza; POLESELLO, Giancarlo CavalliAbstract In the last 15 years, the diagnosis of femoroacetabular impingement has become more frequent; with the advance of surgical indications, different techniques have been developed. Surgical treatment includes a wide variety of options, namely: periacetabular osteotomy, surgical hip dislocation, arthroscopy with osteochondroplasty via a small incision, modified anterior approach technique, and exclusively arthroscopic technique. The type of approach should be chosen according to the complexity of the morphology of the femoroacetabular impingement and to the surgeon's training. The techniques most used today are arthroscopy, surgical dislocation of the hip, and periacetabular osteotomy. The present article aims to describe the current main surgical techniques used to treat femoroacetabular impingement, their indications, advantages and disadvantages, complications and clinical results.
- Femoroacetabular Impingement and Acetabular Labral Tears – Part 2: Clinical Diagnosis, Physical Examination and Imaging(2020) POLESELLO, Giancarlo Cavalli; EISJMAN, Leandro; QUEIROZ, Marcelo C.; RUDELLI, Bruno Alves; RUDELLI, Marco; RICIOLI JUNIOR, WalterAbstract The clinical diagnosis of femoral acetabular impingement (FAI) continues to evolve as the understanding of normal and pathological hips progresses. Femoral acetabular impingement is currently defined as a syndrome in which the diagnosis consists of the combination of a previously-obtained comprehensive clinical history, followed by a consistent and standardized physical examination with specific orthopedic maneuvers. Additionally, radiographic and tomographic examinations are used for the morphological evaluation of the hip, and to ascertain the existence of sequelae of childhood hip diseases and the presence of osteoarthritis. The understanding of the femoral and acetabular morphologies and versions associated with images of labral and osteochondral lesions obtained through magnetic resonance imaging (MRI) contributes to the confirmation of this syndrome in symptomatic patients, and helps in the exclusion of differential diagnoses such as iliopsoas tendon snaps, subspine impingement, ischiofemoral impingement, and other hip joint pathologies.
